| 9 | Ionic liquid modified Pt/C electrocatalysts for cathode application in proton exchange membrane fuel cells显示文摘The modification of Pt/C catalyst by using ionic liquids to improve their catalyst activities has been reported by many researchers,but their practical behavior in operating fuel cells is still unknown.In this work,we study the ionic liquid modified Pt/C nanoparticle catalysts within cathodes for proton exchange membrane fuel cells.The influence of the ionic liquid amount,adsorption times and dispersing solvents are investigated.The experiment results show the best performance enhancement is achieved through two-time surface modification with 2 wt-%ionic liquid solution.The mechanisms are explored with the attribution to the high oxygen solubility in the ionic liquid enabling an improved oxygen diffusion in micropores and to good hydrophobicity facilitating water expelling from the active sites in fuel cell operation. | Huixin Zhang Jinying Liang Bangwang Xia Yang Li Shangfeng Du | 2019 | Frontiers of Chemical Science and Engineering2019，13，4： | 4 |

| 11 | Chemical functionalization of 2D black phosphorus显示文摘As an emerging two-dimensional material,black phosphorus(BP)has fascinating structure and electronic properties,affording broad applications in fieldeffect transistors,optoelectronic devices,energy devices,and biomedicines.However,the lone pair electrons of phosphorus atoms readily react with oxygen,so few-layer BP is easily oxidized and degraded when exposed to air.Therefore,the ambient stability of BP needs to be enhanced for its potential application.Chemical functionalization is one of the most effective methods for improving the ambient stability of few-layer BP.In this review,we provide a comprehensive overview of the chemical functionalization of BP,focusing on covalent and noncovalent functionalization and surface coordination.The influence of the functionalization pattern on the electronic properties and ambient stability of BP is summarized.Finally,the challenges and future development of chemical functionalization of BP are discussed. | Yajuan Liu Muqing Chen Shangfeng Yang | 2021 | InfoMat2021，3，3： | 2 |

| 15 | The occurrence of vanadium in nature:its biogeochemical cycling and relationship with organic matter—a case study of the Early Cambrian black rocks of the Niutitang Formation,western Hunan,China显示文摘Vanadium in the black rocks has economic and environmental impacts.In sediments,it is broadly disseminated as a multivalent metal element mainly sensitive to redox settings.Globally in petroleum,it is considered an abundant component.Vanadium is an essential tool to determine the relationship of the Earth with extra-terrestrial bodies.In the Yangtze region,the black rocks of the Early Cambrian Niutitang Formation are highly enriched in the concentration of V,Co,Ni and Mo.These sediments are comprised of a high total organic carbon content,and the average concentration of vanadium is over 240 ppm.Here we discuss the mechanisms and conditions that were responsible for the accumulation of vanadium in these black sediments in the Yangtze region.The oxygenated ocean water is favorable for the dissolved vanadate species Ⅴ(Ⅴ).Therefore,in oxic ocean-water,it can be reduced by organic matters or by H_(2)S to vanadyl ions Ⅴ(Ⅳ),which can facilely be adsorbed to the tiny particles and finally deposit into the sediments with the settling of the particles.The presence of V_(2)O_(3) in the Niutitang Formation indicates the isomorphism state of vanadium existence in the clay minerals.Clays and pyrite are the most favorable mineral for vanadium enrichment.However,it is suggested the quartz of non-biogenic origin might be unfavorable for vanadium enrichment.Vanadium is mainly derived from the diagenetic transformation of its precursor(porphyrin pigments and chlorophyll)from the organism.During the Early Cambrian period,the massive transgression in the sea level created a favorable environment for organisms to survive.Additionally,the hydrothermal activities brought massive nutrient supply in the form of vanadium and other metal elements from the deep Earth.These creatures consumed the vanadium-rich nutrients,which became a part of their bodies in the form of hard and soft parts.Later on,when these organisms died and were submerged in the sediments.After the diagenetic actions,this vanadium became a part of these black sediments along with organic carbon.Therefore,these black rocks in the Yangtze region are enriched in vanadium and organic carbon.It is suggested the various processes such as adsorption,complexation,and reductions are the main factors responsible for the precipitation of dissolved vanadium into the organically rich sediments. | Rizwan Sarwar Awan Chenglin Liu Shangfeng Yang Yuping Wu Qibiao Zang Ashar Khan Guoxiong Li | 2021 | Acta Geochimica2021，40，6： | 1 |

| 17 | Experimental study of CT test on the failure of acrylate spray-applied waterproof layer in the groundwater environment显示文摘In this study the computerized tomography (CT) was first used to quantitatively analyze the failure of acrylate spray-applied waterproof membrane in the groundwater environment. The results of the CT tests show that it is feasible to use the CT to quantitatively analyze the failure of the waterproof membrane and the CT method has the advantages of speediness and accuracy that can eliminate the fussy operation process in routine tests. The main conclusions summarized from the study are as follows. First, there are two combined-indexes that can be used to decide the failure of the spray-on waterproof layer: one is that the reduced percentage of the CT number of the spray-on waterproof layer is less than 40.0% and the other is that the variance of the CT number decreases first and then increases. Second, the applicability for the spray-on waterproof layer in the groundwater environment is the SO 24-concentration ≤ 1%, the Cl-concentration ≤ 7.5% and the pH value ≤ 12.0 of the groundwater, respectively. | YANG QiXin, XU Peng & ZHENG ShangFeng 1 School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031, China | 2010 | Science China(Technological Sciences)2010，53，2： | 1 |

| 20 | Conductivity enhancement of PEDOT:PSS film via sulfonic acid modification: application as transparent electrode for ITO-free polymer solar cells显示文摘3-Hydroxy-1-propanesulfonic acid(HPSA)was applied as a modification layer on poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)film via spin-coating,resulting in a massive boost of the conductivity of PEDOT:PSS film,and thus the as-formed PEDOT:PSS/HPSA bilayer film was successfully used as a transparent electrode for ITO-free polymer solar cells(PSCs).Under the optimized concentration of HPSA(0.2 mol L^(-1)),the PEDOT:PSS/HPSA bilayer film has a conductivity of 1020 S cm^(-1),which is improved by about 1400 times of the pristine PEDOT:PSS film(0.7 S cm^(-1)).The sheet resistance of the PEDOT:PSS/HPSA bilayer film was 98Ωsq^(-1),and its transparency in the visible range was over 80%.Both parameters are comparable to those of ITO,enabling its suitability as the transparent electrode.According to atomic force microscopy(AFM),UV-Vis and Raman spectroscopic measurements,the conductivity enhancement was resulted from the removal of PSS moiety by methanol solvent and HPSA-induced segregation of insulating PSS chains along with the conformation transition of the conductive PEDOT chains within PEDOT:PSS.Upon applying PEDOT:PSS/HPSA bilayer film as the transparent electrode substituting ITO,the ITO-free polymer solar cells(PSCs)based on poly[N-9″-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)]:[6,6]-phenyl C71-butyric acid methyl ester(PC_(71)BM)(PCDTBT:PC_(71)BM)active layer exhibited a power conversion efficiency(PCE)of 5.52%,which is comparable to that of the traditional ITO-based devices. | Zhiqiang Zhao Qing Liu Wenfeng Zhang Shangfeng Yang | 2018 | Science China Chemistry2018，61，9： | 1 |
